RQOFERS SEAMlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 552,061, dated December24, 1895.

Application filed April 24, 1894. Serial No. 508,867- (No model.)

To all whom it may concern:

Be it known that LWILLIAM L. HEBERLING, a citizen of the United States,residing at Havana, in the county of Mason and State of Illinois, haveinvented a new and useful Improvement in Roofers Scanning-Tools, ofwhich the following is a specification.

My invention relates to tools for forming double-lock standing seams inmetal roofing, and has for its object to provide a tool that willperform all the operations of double seaming by the simple outwardmovement of two common handles, dispensing with footpower and the use ofa second tool to com plete the work. The mechanism by which I attainthis object is illustrated in the accompanying drawings, throughoutwhich like parts are designated by similar numerals.

Figure 1 is a perspective view of my improved tool with jaws open. Fig.2 is an end View of the same with jaws closed. Fig. 3 is a perspectiveview of my raising-frame and accompaniments. Fig. 4 is an end view ofthe tool with jaws slightly open and the raising-frame locked up in idleposition. Fig. 5 is aperspective of the central jaw of the tool lying onits side. Fig. 6 is a side elevation of the tool with a segment cut awayto show how the coil-spring acts on the raising-frame through the hinge.Fig. 7 shows the upper part of a cross-section taken at the line X X,Fig 6,while the raising-frame is down in working position. Fig. Sis aview of the same parts shown in Fig. 7 as they appear when theraising-frame is up, as in Fig. 4.

This seamer consists of three jaws and a raising-frame. Two adjacentjaws 1 and 2 are hinged together and provided with handles 1 and 2,Figs. 1 and 4. The third jaw 3 is pivotally connected with both theothers and automatically operated by them. The central jaw 2 is providedwith hinge-lugs which project sidewise into corresponding depressionsformed for them in the jaw 1, and the interlapping parts thus broughttogether are hinged by a light rod which passes through them from oneend of the jaws to the other, Figs. 1, 2, 4 and 5. The angular jaw 3 isprovided with lugs 3 3", which are hinged to lugs 2" 2 of the centraljaw 2', Figs. 1, 2, 4 and 6. The two outside jaws are connected togetherby links 5 5, which unite the lugs 1 1 of the jaw 1 with the lugs 3 ofthe jaw 3, Figs. 1, 2, 4 and 6.

The raising-frame 4, Fig. 3, is hinged to the lugs 2 2" of the centraljaw 2 by the bolt 6, Figs. 1, 2, 3, 4 and 6. The bolt 6, which supportsthe raising-frame 4, also serves in conjunction with the thimble 6,Figs. 3 and 6, as a hinge-rod for the lugs 2 and 3" referred to, Figs. 1and 6. The thimble 6 is inserted on the rod 6 at the end of a compressedspiral spring which surrounds the rod with one end against the lug 2 andthe other against the thimble, Fig. 6,'thus causing the thimble tocommunicate the pressure from the spring endwise against theraising-frame so as to force it endwise and engage its lockingmechanism. .The right-hand end of the raisingframe, as shown in Figs. 1,3 and 6, is enlarged and has a projection 4, which may engage eitherside of the adjacent lug 2", and thus limit the swing of theraising-frame. The lugs of the raising-frame are far enough apart togive it a quart-er of an inch play endwise with the rod 6 outside of thelugs 2, Figs. 1 and 6, so that while the compressed spring naturallyholds the frame endwise with the projection 4 in engagement at the sideof the lug 2 the operator may force the frame and thimble back againstthe spring far enough to release the projection 4 and bring it out onthe edge face of the lug 2", and when thus released the position of theframe may be changed either from that shown in Figs. 1, 2 and 6 to thatshown in Fig. 4, or vice versa. In these different positions theprojection 4 engages opposite sides of the lug 2", as shown in Figs. 7and 8. Fig. 7 shows the position of 4 to 2" while the raising-frame isin working position, as in Figs. 1, 2 and 6. Fig. 8 shows the positionof 4 to 2 while the frame is up with its base against the handle 2, asin Fig. 4. Vhen the frame is swung down the stop 8 comes in contact withthe lower part of the jaw 2 at the notch 8, Fig. 3, which limits itsdownward swing just as it has reached its proper working position.Additional means for locking the raising-frame in this position andsupporting it at its base are provided by the catches 7 7, Fig. 3, andnotches 7 7, with their extensions 7 7, Fig. 5, which are entered bysaid catches when the projection 4 escapes from the edge of the ing 2',which permits the frame to move endwise, thus securing the rigidposition of the fame until it is again released, as before described.

The operation of this tool is very simple. It is apparent that theoutward movement of the handles operates all the jaws simultaneously,and that the jaw 3 is used with the central jaw for starting the folds,and that the jaw l is used with it for clamping them down.

In turning and clamping down the first fold of a double seam the tool isused with the raising-frame under it, as in Figs. 1, 2 and 6, and inturning and clamping down the second fold it is used with theraising-frame locked up in idle position, as in Fig. 4:.

What I claim as new, and desire to secure by Letters Patent, is

1. In a roofers seaming tool, ihree jaws each two of which are hinged orlinked together on a pivotal line separate from that on which either ofthem is connected with the remaining jaw; all arranged to be broughttogether simultaneously by operating mechanism.

2. In a roofers seaming tool, three jaws each two of which are hinged orlinked together on a pivotal line separate from that on which either ofthem is connected with the remaining jaw; all arranged to be broughttogether simultaneously by the operation of two handles.

3. In a roofers seaming tool, two jaws hinged together as a seam clamp,in combination with a third jaw which is pivotally connected with eachof them above the pivotal line of their connection with each other.

4. In a roofers seaming tool, two jaws hinged together as a seam clamp,in combination with a third jaw which is hinged or pivoted to the clampjaw nearest it above the pivotal line of the clamp hinge, and betweenthe pivotal lines of the said two hinges is connected by links with thefarther clamp jaw.

5. In a roofers seaming tool, a central jaw which is adapted to restwith its base on the roof while at work and is provided with two outsidejaws which are adapted to close against it, in combination with a hingedraising frame which is adapted to work under said central jaw, or to beswung out therefrom.

6. I11 a roofers seaming tool, a central jaw which is adapted to restwith its base on the roof while at Work and is provided with two outsidejaws which are adapted to close against it, in combination with a hingedraising frame which is adapted to work underneath said central jaw, orto be swung out therefrom, and is provided with an automatic lockingdevice.

7. In a roofers seaming tool, two opposing jaws which are hingedtogether above their working faces, one of which jaws is adapted to reston the roof while at work and is provided on one side with a rigidlongitudinal lip which is adapted to bend the seam flanges at rightangles over the edge of the opposing.

jaw, in combination with a raising frame which is hinged to said lippedjaw and is adapted to work underneath it or to be swung out therefrom.

S. In a roofers seaming tool, two opposing jaws which are hingedtogether above their working faces, one of which jaws is adapted to rest011 the roof while at work and is provided on one side with a rigidlongitudinal lip which is adapted to bend the seam flanges at rightangles over the opposing jaw, in combination with a raising frame whichis hinged to said lipped jaw and is adapted to work underneath it or tobe swung out therefrom, and to be locked in position by an endwisemovement.

9. In a roofers seaming tool, two opposing jaws provided with operatingmechanism, in combination with a raising frame or bar which is providedat its ends with hinge lugs which both stand outside of correspondinglugs on one of the said opposing jaws, and are hinged therewith by a pinor bolt on which a coil spring is carried between the said lugs of thesaid jaw, one end of said spring engaging the inner side of one of thesaid jaw lugs and the other end arranged with means to communicatepressure through the hinge-bolt hole of the opposite said jaw lug to theadjacent lug of the raising frame, said frame being adapted to be thusforced endwise and locked.
